I have a 6700w Solar panel system on my roof.
I use a programmable thermostat and keep my heating temp fairly low.
I use CFLs in over half my lights in the house and especially in the lights that are on the most.
I have completed installation of new double paned high RF windows.
I wrapped my water heater in RF 15 Fiberglass insulation.
When I purchased my new Oil burning Furnace, I ensured it was over 90% efficient.
I look for energy efficient appliances.
I bought an LCD TV that uses half the energy of the same size Plasma, 66% as a DLP and 66% of the 32" Tube TV that we use to use as the main set.
My primary computer has an LCD instead of CRT.
I compost all of my lawn debris. However, I am not sure of the net value of this over a dump except that there is not transport carbon at least.
Small one, but I use cloth bags as much as possible.
My next car will be a Hybrid. This will be in 1-3 years when my cheap little Ford Focus that I put 20k per year on, dies.
As they become available for reasonable prices, I will start installing LED lighting solutions.
My next water heater will probably be a tankless system.
I will eventually add more Solar Panels unless I can further reduce my energy use.
I am teaching my kids to conserve energy and why we should.
I try to educate people both here at the SDMB and in my county about the environment and how energy conservation in homes could be a measurable part of the reduction of Green House Gases.
